Our Frontier series solutions are available in two primary fuel configurations, each engineered to address specific geographic, logistical, and environmental requirements. The Tier 4 Final (4F) Diesel option represents the cleanest diesel emission standard available, utilizing advanced aftertreatment to reduce particulate matter and nitrogen oxides by over 90%. This configuration is the premier choice for properties without natural gas service or remote locations where propane delivery is challenging. It is particularly well-suited for customers who prioritize on-site fuel autonomy, as diesel can be stored in large quantities and treated with stabilizers to extend its shelf life for up to two years, ensuring mission-critical performance even in the most isolated environments.

Alternatively, our Natural Gas and Propane (NG-LPG) units provide a clean-burning gaseous fuel solution with the potential for an unlimited supply. This option is ideal for homes and businesses with existing natural gas infrastructure or properties utilizing large-scale propane tanks. Customers prioritizing lower long-term operating costs and reduced maintenance often select this configuration, as gaseous fuels do not suffer from the degradation issues common with liquid fuels. These units are especially effective for microgrids, nano-grids, and extended outages where a continuous fuel supply is required to outlast the limits of on-site diesel reserves.
